Differential Habituation Of Male Betta Splendens To Qualitatively Different Stimuli, Lauren Baard
Differential Habituation Of Male Betta Splendens To Qualitatively Different Stimuli, Lauren Baard
Undergraduate Research Symposium (UGRS)
Habituation is a learning mechanism that functions to decrease the amount of energy and attention focused on a certain stimuli. Male Siamese Fighting Fish, Betta splendens, are territorial animals that defend their territories using a number of aggressive displays. Male Bettas have previously shown the ability to habituate to the presence of a conspecific male when visually exposed to each other. Due to the costly nature of many of the male Betta’s displays, I hypothesized that male Bettas should differentially habituate to qualitatively different stimuli. I presented each of three groups of male Betta splendens with a different stimulus, each …

Predator Survival Tactics And Use Of Habitat Cover In Rana Catesbeiana., Tara E. Bergin
Undergraduate Research Symposium (UGRS)
Predator-prey relationships are an important aspect of the natural world, and, because of its relevance to survival and natural selection, is an interesting relationship to study. In amphibian larvae, level of activity and landscape use are often what determines the survival as prey. I studied the anti-predator behavior of the North American bullfrog (Rana catesbeiana) tadpoles when presented with dragonfly (Aeshna) larvae, a known predator of tadpoles. Tadpoles were acclimated to four different habitats with varying degrees of habitat cover, and were transferred to a new habitat with a degree of cover equal to one of the acclimation tanks. A …

Climate Change And Its Effects On Polar Bears, Alex C. Jospe, Bethany C. Peck, Emily Sinnott
Undergraduate Research Symposium (UGRS)
Polar bears are key indicators of the effects of climate change on the arctic ecosystem, because their existence is directly related to the sea ice habitat, where they hunt. As the Arctic continues to warm, their habitat will be reduced further and local extinction is likely to occur, especially in southern populations.
